• OPERATION
The key to efficient operating is controlling the pressure
and surface contact between the wheel and workpiece
(Fig. 10). Flat surfaces are ground at an acute angle,
usually at a 10 to 20 angle with the work piece. (Fig. 11)
Too great an angle causes concentration of pressure on a
small area which may gouge or burn work surface.
